Niamey Patented Sept. 5, 1933 UNITED STATES PATENT OFFICE BoxApplication February 18, 1929, Serial No. 340,697 Renewed July 24, 19331 Claim. (Cl. 229-14) My invention relates to paper boxes and has forits object to provide a paper box having a reinforced bottom therein.

Another object of the invention resides in providing a box having sidesand in providing flaps on said sides adapted to be bent inwardly to forma bottom and to further provide a false bottom superimposing saidbottom.

A still further object of the invention resides in providing strutsbetween said bottom and false bottom and in attaching some of saidstruts to the bottom and other of said struts to said false bottom.

Another object of the invention resides in forming said struts bybending portions of said bottom and false bottom outwardly at rightangles thereto. Y

A feature of the invention resides in disposing the struts on saidbottom in different relative positions with respect to the'struts onsaid false bottom.

Another object of the invention resides in forming the struts on thebottom of the box by bending the marginal portions of the meeting edgesof said flaps at right angles to said'flaps, and in positioning saidedges adjacent one another so as to cause the same to engage one anotherand hold the strut in erect position.

A still further object of the invention resides in bending the marginalportions of said false bottom to form the struts thereon, and in makingthe size of said false bottom such as to cause ,Nsaid struts to engagethe sides of the box to be held, in erect position by engagementtherewith.

A feature of the invention .resides in constructing the box so that thesame, together with the false bottom, may be readily collapsed andpacked in a fiat state. Other objects of the invention reside in thedetails of construction thereof and in the novel combination andarrangement vof parts hereinafter illustrated or described.

In the drawing:

Fig. 1 is a perspective View of a box illustrating an'embodiment of myinvention with a portion of the sides thereof cut away to show theinterior Vconstruction of the box.

Fig. 2 is an elevational sectional view illustrating the box in closedposition and taken along )une 2 2 of Fig. 1.

Fig. 3 is a developed view of the blank from which the box proper ismade.

Fig. 4 is a developed view of the blank from' have shownla boxcomprising a body portion 10 which is constructed from a blank 11 formedof a single sheet of material such as is indicated in Fig. 3. The body10 comprises end walls 12 and 13 and side walls 14 and 15 which areformed by 60 scoring the blank 11 along two longitudinal lines 16 and 17and along three transverse lines 18, 19 and 20. The box is constructedby folding the blank along the score marks 18, 19 and 20 and bringingthe edges 21 and 22 together at a corner65 of the box. These edges maybe secured together as by gluing a reinforcing strip along the corner ofthe box or by metal clips, or by gluing the overlapping portions of theflaps together, or in any other suitable manner.

A number of flaps 23, 24, 25 and 26 extend outwardly from the edges ofthe sides 14 and 15 of the box, while similar flaps 27, 28, 29 and 30yextend outwardly from the edges of the ends 12 and 13 of the box. Theseflaps are formed by 75 severing the stock of the blank 11 along lines 31which are in alignment with the score marks 18, 19 and 2O and whichextend from the edge of the stock up to the score marks 16 and 17. Thesevarious flaps are adapted to be folded inwardly at' right angles to theside and end walls of the box to provide top and bottom closurestherefor.

Adjacent theouter edges of the blank 11, I provide two score marks 32and 33 which extend completely across all of the flaps and form shorttabs 34, 35, 36, 37, 38, 39, 40 and 41 at the ends of the aps. Thesetabs are adapted to be bent at right angles to the respective flaps onwhich they are attached and when said iiaps are arranged to close thebox, said tabs extend inwardly into the box to provide struts which Ihave indicated in their entirety in Fig. 1 at 50 and 51. In theconstruction of the box, the length of the flaps 27, 28, 29 and 30 isequal to one-half the length of the side Walls 14 and 15 so that whenthese iiaps are folded into closed "position, the tabs 36 and 41 onflaps 27 and 30 meet one another in the center of. the box, andsimilarly the tabs 3'? and 41 of flaps 28 and 29 meetone another in Athecenter of the box. Due to the engagement of the respective flaps withone another, as illustrated, the said flaps are held in erect positionto form the struts 50.

Along the center of each of the flaps 27, 28, 29 and 30 is formed a slot42 which extends from the edge of the blank up to the respective scoremarks 16 or 17. When the various flaps 27, 28, 29 and 30 are folded intoclosing position, the slots extend in continuous formation across thepartial no closure formed by said flaps. The flaps 23, 24, 25

and 26 are made of a lengthequal to one-half the length of the end walls12 and 13 of the box so that when the same are folded into closingposition, the tabs 34, 35, 38 and 39 lie adjacent to one another alongthe meeting edges of said flaps and are adapted to be received' withinthe slots 42 extending across the aps 2'7, `28, 29 and 30 so as toextend into the interior of the box .proper and form additional struts51 which intersect the struts 50, as best shown in Fig. 1. These strutsare similarly held in erect position through the engagement of thecomponent tabs thereof with one another.

In conjunction with the bottom structure of the box, I employ a falsebottom 52 which is constructed from a blank 53 shown in detail in Fig.4. This blank is scored along lines 54, 55, 56 and 57 near the edges ofthe blank, to provide marginal tabs 58, 59, 60 and 61 of a height equalto the height of the struts 50 and 51. These tabs are adapted to be bentat right angles to the plane of the false bottom 52 to provide struts 62issuing outwardly from the false bottom at the edges thereof. The falsebottom 52 is preferably of such a size as to t snugly within the box sothat the various tabs 58, 59, 60 and 61 thereof engage the walls 12, 13,14 and 15 of the box, and are held in erect position through engagementtherewith.

In the use of the device, the false bottom 52 is inserted into the boxproper and in inverted rela.- tion with respect to the bottom 63thereof. For the reception of the ends of the struts 50 and 51,

notches 64 are cut in the" various tabs 58, 59, 60

and 61 which receive the said strut ends and serve to assist in holdingthe same in erect position. At the corners of the blank 53 are cutnotches, designated at 65, which form ears 66. These ears are bent atright angles along the score marks 54 and 55 and are folded back intothe plane of the adjoiningtabs to reinforce the struts attached to thefalse bottom.

When the false bottom. 52 has been installed within the box, the variouscorners of the box and the seams situated between the flaps Aforming thestruts 50, may be sealed by means of any suitable adhesive tape. When soconstructed, a box with a suitably reinforced bottom is provided,capable of sustaining an appreciablev weight. It will be noted that thestruts formed on the false bottom are disposed at relatively differentposition to the struts formed on the bottom proper so that sufficientreinforcement is provided throughout the entire area of the bottom so asto effectively withstand the weight placed upon the same.

In the drawing, I have illustrated only the bottom and top of the box asconstructed in accordance with my invention to reinforce the same,though it' can readily be comprehended that other walls of the boxstructure can be similarly constructed if desired, and where I have usedthe terms bottom and false bottom, these terms refer to any of the wallsof the box structure. Likewise, in the drawing, the box shown is ofsquare formation though boxes of rectangular form in which the sides arenot of the same length may be equally as well constructed embodying theprinciples of my invention.

My invention is highly advantageous in that it provides a simple andeffective reinforcing structure for paper boxes whereby an appreciableweight may be placed upon the bottom of the box. The removal of thesubstance from the corners of the box serves to reduce the breakage ofthe box where the strain upon the same is the greatest. The box can beconstructed at a nominal cost and from stock material by machineryordinarily available for the y"manufacture of paper boxes. The box maybe collapsed and packed in a compact state for shipment and storage whennot desired for use.

Changes in the specific form of my invention, as herein disclosed, maybe made within the scope of what is claimed without departing from thespirit of my invention.

Having described my invention, what I claim as new and desire to protectby Letters Patent is:

A box comprising a bottom, struts integral with said bottom and issuinginwardly therefrom, a false bottom superimposing said bottom, strutsintegral with said false bottom and extending toward said bottom, all ofsaid respective bottom and false bottom struts intersecting one another.
